Okay, we are stuck at dash wiring for our MK4 build.

We have wired the autometer gauges per the instructions (I think). See pics below and let me know if you have any input.

Seems like the gauges are not getting power. Keep in mind, we are total noobs and have no prior experience... so don't be afraid to mention the obvious, it's not obvious to us.

An observation I had is that the volt meter seems not to have any place to ground. Seems like an issue to me, but I might be misunderstanding too.
Thanks in advance for any insights or help.

Small gauge cluster:


Speedometer:


Tachometer:


Not sure if this is the issue or not but, as you can see... we have not wired the headlights and turn indicators:


Lastly, we cannot figure out where to connect the green wire for the fan. I believe this is the thermostat switch to turn the fan on:
